I have created C++ FFT sample project, open one of it's files, the opened Tools->Options->Editor clicked somewhere. Then tried to quickly open several files not waiting when each of them is finished to be opened. => i've got an exception, but can not report it from IDE, because it is hang. Exception is: SEVERE [org.openide.util.RequestProcessor]: Error in RequestProcessor org.openide.text.CloneableEditor$DoInitialize java.lang.IllegalStateException at org.openide.text.CloneableEditorSupport.prepareDocument(CloneableEditorSupport.java:595) at org.openide.text.CloneableEditor$DoInitialize.initNonVisual(CloneableEditor.java:377) at org.openide.text.CloneableEditor$DoInitialize.run(CloneableEditor.java:320) at org.openide.util.RequestProcessor$Task.run(RequestProcessor.java:602) at org.openide.util.RequestProcessor$Processor.run(RequestProcessor.java:1084) Caused: org.openide.util.RequestProcessor$SlowItem: task failed due to at org.openide.util.RequestProcessor$Task.schedule(RequestProcessor.java:655) at org.openide.text.CloneableEditor$DoInitialize.<init>(CloneableEditor.java:287) at org.openide.text.CloneableEditor.initialize(CloneableEditor.java:222) at org.openide.text.CloneableEditor.componentShowing(CloneableEditor.java:198) at org.openide.windows.WindowManager.componentShowing(WindowManager.java:332) at org.netbeans.core.windows.WindowManagerImpl.componentShowing(WindowManagerImpl.java:1022) at org.netbeans.core.windows.view.DefaultView.changeGUI(DefaultView.java:161) at org.netbeans.core.windows.ViewRequestor.dispatchRequest(ViewRequestor.java:269) at org.netbeans.core.windows.ViewRequestor.processRequest(ViewRequestor.java:245) at org.netbeans.core.windows.ViewRequestor.postRequest(ViewRequestor.java:183) at org.netbeans.core.windows.ViewRequestor.scheduleRequest(ViewRequestor.java:123) at org.netbeans.core.windows.Central.activateModeTopComponent(Central.java:1760) at org.netbeans.core.windows.WindowManagerImpl.topComponentRequestActive(WindowManagerImpl.java:1145) at org.openide.windows.TopComponent.requestActive(TopComponent.java:789) at org.openide.windows.CloneableOpenSupport$1.run(CloneableOpenSupport.java:99) at org.openide.util.Mutex.doEvent(Mutex.java:1335) at org.openide.util.Mutex.writeAccess(Mutex.java:452) at org.openide.windows.CloneableOpenSupport.open(CloneableOpenSupport.java:95) at org.openide.text.CloneableEditorSupport.open(CloneableEditorSupport.java:463) at org.openide.awt.ActionDefaultPerfomer.actionPerformed(ActionDefaultPerfomer.java:67) at org.openide.awt.ContextAction$Performer.actionPerformed(ContextAction.java:223) at org.openide.awt.ContextManager.actionPerformed(ContextManager.java:241) at org.openide.awt.ContextAction.actionPerformed(ContextAction.java:106) at org.netbeans.modules.openide.util.ActionsBridge$ActionRunnable$1.run(ActionsBridge.java:108) at org.netbeans.modules.openide.util.ActionsBridge.implPerformAction(ActionsBridge.java:83) at org.netbeans.modules.openide.util.ActionsBridge.doPerformAction(ActionsBridge.java:67) at org.openide.awt.GeneralAction$DelegateAction.actionPerformed(GeneralAction.java:218) at org.openide.explorer.view.TreeView$PopupSupport.mouseClicked(TreeView.java:1544) at java.awt.AWTEventMulticaster.mouseClicked(AWTEventMulticaster.java:253) at java.awt.AWTEventMulticaster.mouseClicked(AWTEventMulticaster.java:252) at java.awt.AWTEventMulticaster.mouseClicked(AWTEventMulticaster.java:252) at java.awt.AWTEventMulticaster.mouseClicked(AWTEventMulticaster.java:252) at java.awt.Component.processMouseEvent(Component.java:6266) at javax.swing.JComponent.processMouseEvent(JComponent.java:3267) at java.awt.Component.processEvent(Component.java:6028) at java.awt.Container.processEvent(Container.java:2041) at java.awt.Component.dispatchEventImpl(Component.java:4630) at java.awt.Container.dispatchEventImpl(Container.java:2099) at java.awt.Component.dispatchEvent(Component.java:4460) at java.awt.LightweightDispatcher.retargetMouseEvent(Container.java:4574) at java.awt.LightweightDispatcher.processMouseEvent(Container.java:4247) at java.awt.LightweightDispatcher.dispatchEvent(Container.java:4168) at java.awt.Container.dispatchEventImpl(Container.java:2085) at java.awt.Window.dispatchEventImpl(Window.java:2475) at java.awt.Component.dispatchEvent(Component.java:4460) at java.awt.EventQueue.dispatchEvent(EventQueue.java:599) at org.netbeans.core.TimableEventQueue.dispatchEvent(TimableEventQueue.java:125) at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:269) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:184) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:174) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:169) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:161) [catch] at java.awt.EventDispatchThread.run(EventDispatchThread.java:122)
